When you say that it "ran well" for the first 1100 miles, are you saying
that it truly performed as expected.....started well, idled well, accelerated
well, etc?
If so, that should rule out a few first time engine rebuild mistakes like
incorrect valve timing which was my first reaction when I read the items
you eliminated.
Some things come to mind: if you checked cylinder compression just after
the rebuild, check it again now (I'm thinking head gasket here); check the
timing - getting a strong spark is great but kind of useless if it's not
happening when it should; sounds like you're getting fuel since the plugs are
wet - maybe too much fuel - could the carb fuel bowl valves be sticking or
are the floats set incorrectly? While it's idling badly, does the engine
react any differently if you pull the choke out?
All this said and thinking optimistically (since the engine ran well for
1100 miles).....I think I'd first zero in on the carbs and the float valves.
I've seen situations after rebuilds or restorations when some little
piece of crud in the fuel line, that you thought you blew out well, finally
works its way into the carbs and clogs one or both of the fuel bowl valves
enough to stick them open and flood the carbs. Try tapping the bowls while
the engine is idling (use the wooden handle of the hammer!)......sometimes
that's all you need to break the dirt free.
